Gigabytes of editor log during a build due to this message

My editor log file can get well into 70-100gb in size due tot the following informational message…

how to tun this off as it makes the build horrifically slow appending messages to a file that is tens of gigabytes in size?

this informational message only appears while compiling shader variants - up until this point it is not visible in the logs.
